Posted by on Sunday, March 13, 2016

A magnitude 6.3 earthquake struck 65 kilometers south-southeast of Atka, Alaska at 18:06 UTC.

The United States Geological Survey recorded the tremor 51 miles south of Atka, Alaska at 10:06 a.m. 

The earthquake was not expected to generate a tsunami, according to the National Weather Service Tsunami Alerts.

Earlier in the day, a 4.2-magnitude earthquake rocked Southern California.

The Aleutian arc extends approximately 3,000 km from the Gulf of Alaska in the east to the Kamchatka Peninsula in the west. It marks the region where the Pacific plate subducts into the mantle beneath the North America plate. This subduction is responsible for the generation of the Aleutian Islands and the deep offshore Aleutian Trench.
